'noma To all whom 't may con-cem:

Be-it known that I, OLIVER New Jersey, have invented and discovered cation;

My said nventon relates to bombs, or

projectiles of the explosive type, and con- X sists in the combinations and arrangements of elements hereinafter described and particularly set fol-th in the accompanying claims. A

The i nvention has for its purpose to proe vide a bomb adapted for destroying or disabling submarines, defiecting torpedoes, and making warfare against such means of attack, and which may be fired from the air, from guns, 'or from the shore, by hand or by any type of bomb thrower now in use.

A further purpose of the invention is toproduce a bomb, or projectile, adapted to be I exploded by an electric current in a circuit arranged to be completed or closed by the action of the water as soon as the bomb is dropped therein; and having safety means for preventin'g premature explosion while the bomb is being handled or through other cause.

The invention is disclosed by way of illustration in the accompanying drawing which shows a central vertical sectional View of the bomb.

Referring to the Construction in further detail the bomb consists of a casing 1 preferably of spherical form having an open ended and cylindrical extension or neck 2, and constructed preferably of metal of suitable thickness; The spherical portion l of the casng contains an explosive charge 3 having embedded therein the electrical means for igniting said charge when the bomb is submerged in water, and the cylindrical portion 2 contains the circuit closing means to produce gnition of the primer and the safety device employed.

The ignition device conssts of a battery 4' contained in a suitable 'receptacle 5, and 6 and 7 designate the conductor wires from the battery as shown. A resistance 8 is located in the conductor wires 7 and is utilized as one of the means for igniting the charge 3 to eX- V plode the bomb.

A coil 9 located in the c'asing 10, and connected to the battery, induces a current in specifieation of Letters i T. HuIGnR FORD, a citizen *of the United States, resdng" at Belleville, Essen County, andState ot Patented Mar, 22, 1921.?

eXplode-the charge. 'The shunt wire l is reliedon to ignite the charge through'the 'resistance 8 in the event of failure of the coil. i

Otherwise the current that would pass through the wire 16 would be neglgible.

The two wires 6 and 7 are led through a disk 13 and then through a suitable insula- 'tion' 14: in the cylindrical part 2, andthe ends of said wires are embedded in aremovable safetycap. 15 inserted in theend of'thecylinder 2 to protect the ends of the wires until,

the bomb is to be used. A rib 17 is formed between said wires to effectively guard' the ends of the conductors against Contacting with a tool used to remove the cap which tors 6 and'7 are immersed in water, i. e; the i water completes the electric circuit and causes the current to operate to heat the rei r sistance, or the coil to operate the other means, as explained, to ignite' thecharge and produce explosion thereof, through either of the means mentioned.

It isobvious that those skilled in the art may vary the details 'of Construction and arrangement of parts without' departing *fromthe spirit of my invention, and `therer fore I do not wish to be limited to such fea tures except as may be required by the claims.

Having thus described my said invention v what I claim'as new and desire to secure by e Letters Patent, is: t

1.' A projectile comprising a casing having a neck, an explosive charge in the casing, ignition means disposed within the charge, insulating material filling, the neck and forming a depression in the end, conductors passing through the insulating material to the ignition means and having terminals re posed within the depression and a closure for the depression wholly within the neck of the casing and adapted to he manually removed and While in position to maintain the conductors in insulated condition;

2. A projectle comprising a easing, an explosive charge in the casng, ignition means communicatng With the charge, a hollow handle communicatng With the casing, conductors passing through the handle and connected with the ignition means, insulating material filling the handle and maintaining the conductors in spaced relaton, the gap between the V eonductors adapted to be bridged by Water, and manually removable, means to protect the conductors from Water.

3. A ?projectle comprsng a substantielly spherical casing having 'a handle ofiset radially fromone side, an explosive charge Within the czising, insulating material filling the handle and forming a retainer for. the

explosive eharge', an gniting circuit within hollow and maintaining the eXposed terminale against contact.

In wtness Whereof, I have hereunto set my hand and seal at Washngton, D. C.,
